Why Clysar® Polyolefin Films

(There’s a Difference!)

There is a very real difference in the type and brands of shrink films.

Clysar® shrink films are premier-quality polymer materials from a family known as polyolefins.

Our polyolefins offer three key characteristics:

  • Heat-sealable
  • Heat-shrinkable
  • Biaxially oriented (films shrink evenly in both directions)

Unlike commodity shrink packaging, Clysar® films are proprietary, high-performance products, uniquely formulated to deliver targeted shrink characteristics.

Polyolefin Characteristics: Better Performance, Better Package

Clysar offers both polypropylene (hard) and polyethylene (soft) films, providing the industry’s most complete selection of differentiated products.

No matter what the exact type, versatile polyolefin films offer a number of overall advantages:

  • Exceptional clarity and gloss
  • Balanced, even shrink in all directions
  • Enhanced machinability and heat resistance
  • Material safety: non-toxic and inert
  • Excellent stability—won’t discolor, or become brittle with age or freezing temperatures
  • Strong, pinhole-free seals
  • Performs under wide shrink temperature ranges
  • Positive environmental benefits

How Polyolefin Compares
Highlight sections to see details

Polyolefin vs. Corrugate Boxes

  • Typically lower cost per package
  • Uses less material: reduces the product-to-package ratio
  • More efficient to inventory and transport (less space and cost)
  • Uses less resources to produce (trees, water, power)
  • Won’t absorb moisture during processing or transport
  • Protects against tampering, leaks, contamination
  • Clear product view (or opaque security)
  • Easy, frustration-free disposal

Polyolefin vs. PE (Polyethylene Shrink Film)

  • Improved package appearance: crystal clear vs. cloudy optics
  • Typically offers nearly 50% material downgauging opportunity
  • Better performance due to lighter weight
  • Delivers more production uptime—more film on every roll
  • Offers recyclable option for consumer with film available for Store Drop Off through the How2Recycle® Program
  • Tighter, more even shrink performance for crisp package

Polyolefin vs. PVC (Polyvinyl Chloride Shrink Film)

  • Non-toxic and chemically inert—does not contain plasticizers such as DEHP
  • Won’t emit toxic fumes in the manufacturing process
  • Does not corrode packaging equipment, or produce smoke and odor
  • Achieves retailers’ environmental goals of eliminating PVC packaging
  • Allows post-industrial recycling or incineration: won’t release carcinogenic dioxins when incinerated, so waste can be used for industrial fuel
  • Won’t pollute the recycling stream


The polyolefin shrink film used to wrap a typical package accounts for only 1% to 2% of the total packaging material volume.
